There are also a few major things missing; as far as I can see they are exception handling (help needed!), inline assembly, align, synchronized, allocators and monitors (see tickets, basically). And of course there are the as yet unknown bugs the new dstress-based testing might help us catch.

Today I finally persuaded myself to go through all steps to build LDC and make my personal project buildable with LDC.

All I can say is: LDC is f**king awesome. I have a fully optimized Tango-library (-O5 -enable-inlining -release) and an unoptimized build of my OpenGL-app and it already feels much smoother than an optimized DMD build!
